dircolors/ls colors not being displayed correctly using byobu

On my NAS box running Ubuntu 11.04 I'm experiencing an odd issue with dircolors inside byobu. Per the image below, everything works fine outside byobu. The prompt (zsh), vim, and everything else works fine... it's just dircolors that don't appear to be working correctly. One additional note, in Putty on Windows and iTerm2 on OS X I'm using the Solarized color theme.

Steps I've taken to fix, inside byobu:

alake@foxery:~/askubuntu » dircolors -p > ~/.dircolors
alake@foxery:~/askubuntu » echo $TERM >> ~/.dircolors

### Restarted ssh session here

alake@foxery:~/askubuntu » alias ls
ls='ls --color=tty'
alake@foxery:~/askubuntu » echo $TERM && grep $TERM ~/.dircolors
screen-256color-bce
TERM screen-256color-bce
alake@foxery:~/askubuntu » dpkg -la | grep -i byobu
ii  byobu                                     3.33-0ubuntu1.1                            a set of useful profiles and a profile-switcher for GNU screen

iTerm: Putty: - Overriding the alias with ls --color=auto doesn't work.

After a bit more digging I believe this is a bug with byobu, and not a configuration problem as I originally thought. I've filed bug #817690 in Launchpad, where it probably belongs. Thanks for your help everyone!
